  • Publication number: 20240385103
    Abstract: A microscopic and macroscopic evaluation method for a dual-effect hydrate inhibitor is provided. The method is applicable to the performance evaluation of traditional thermodynamic inhibitors and kinetic inhibitors. The present invention comprehensively evaluates the dual-effect hydrate inhibitor microscopically and macroscopically through a microscopic evaluation device and a macroscopic evaluation device, thereby more intuitively and efficiently screening out the dual-effect inhibitor with excellent performance. The present invention explains the action mechanism of the dual-effect inhibitor microscopically, accurately evaluate the effects of the inhibitor in two aspects of particle aggregation and particle adhesion, and provide a theoretical basis for screening the dual-effect inhibitor.

  • Patent number: 12078054
    Abstract: An experimental device and method for co-existence of overflow and lost circulation in a fractured formation during drilling of a deviated well are provided. An inner cavity of an outer pipe is provided with an inner pipe to form a deviated casing. An upper side of the outer pipe is provided with a mixture outlet. A middle-lower side of the outer pipe is provided with a leakage port and two overflow ports. The gap width can be changed by adjusting a bolt and a support block to be compatible with different types of fracture models. A gas injection system includes an air compressor and a gas flowmeter. An upper port of a liquid injection system is connected to a joint arranged at upper ends of the inner pipe and outer pipe through a water pump, a liquid flowmeter and a liquid regulating valve.

  • Patent number: 9691836
    Abstract: A pixel unit is used in an array substrate of a display device. In one embodiment, it comprises a gate line, a source-drain line and a thin-film transistor; and the gate line is in an overlapped structure comprising a first MoW layer, a Cu layer and a second MoW layer overlapped successively; and a gate of the thin-film transistor is formed of the first MoW layer. In another embodiment, the source-drain line is in a same overlapped structure; and a source and a drain of the thin-film transistor are formed of the first MoW layer. The first embodiment is achieved by means of a halftone process while the second embodiment is achieved by means of a lift off process. Diffusion of Cu in the gate layer or in the source-drain layer towards the oxide active layer is prevented.
